QStar Network Migrator

QStar Network Migrator uses advanced policy management to monitor and automatically migrate less frequently used files from departmental and application servers and associated primary storage to a tiered-storage environment or to lower cost archive storage such as an optical or tape library, managed by QStar Archive Manager, Archive Replicator or Data Director software.

Network Migrator Agents are available for Windows, Linux, UNIX, or Mac environments. Integrated support is available for NetApp FPolicy data mover API.

Data migration policies can be defined from either one or a combination of the following administrator-defined criteria:

Date/Time Stamp Criteria
Files can be automatically migrated to QStar Archive Manager based on Creation, Access or Modification Date, such as 180 days from the creation date, or 90 days from the last access of files. This type of file migration policy would ensure that all recently created and accessed files remain on server hard disk for fast access, while moving less-frequently accessed files to an Optical library for data preservation and storage cost savings.

File Extension Criteria
Files can be automatically migrated to QStar Archive Manager based on File Extension, such as all files with a TIF or PDF extension. Alternatively, a file exclusion rule can be created that will migrate all files except those with a certain file extension, such as EXE and DLL.

File Size Criteria
Files can be automatically migrated to QStar Archive Manager when they are larger than, smaller than, or between the range of two file sizes. This type of file migration policy would ensure that only files of a certain size are migrated to the archive.

Disk Space Usage
Files can be automatically migrated to QStar Archive Manager when a certain disk space threshold is reached, such as when available space falls to 10% free on the monitored file system. This type of file migration policy would ensure that remaining server hard disk space never reaches full capacity causing an Out of Disk Space error message.

Data migration policies can utilize:

Stub and Migrate File
A stub containing new file location remains on primary storage, while file is migrated to secondary storage. Regardless of the physical location of the files, they remain fully accessible across the network from their original local file systems. Retrieving the file is as simple as it was before migration. A combination of file attributes can be used to control which information is selected; file creation

Copy File
The file remains in primary storage and a copy is created on secondary storage. This action can be used to pre-migrate data during lower network usage times (at night or weekends).

Move File
The file is removed from primary storage and stored on secondary storage. This can be used to decommission old storage, easily moving files from legacy storage to a new storage device.

In addition to automated file migration from a source file or application server to an archive server hosting an Optical Library or Tape Library, QStar Network Migrator can also manage retention policies by deleting files that meet a policy.

As with the automated file migration policies described above, purge policies can be defined by either one or a combination of the following administrator-defined criteria:

Time Based
Files or file stubs can be automatically purged from primary storage (or QStar Archive Manager) based on a date/time stamp, such as 3 years from the creation date of the file. This type of purge policy would be essential to organizations wishing to destroy files that have met their legal retention period for regulatory compliance.

Extensions
Files can be automatically purged from primary storage based on the File Extension, such as all files with a TMP extension. This type of purge policy would ensure that Temporary Files created by Microsoft Office and other applications are not written to the archive.
